HARLIN HIGGINS, ALBERT L. FISH, AND JAMES L OHARE, or FAITH, sourn DAKOTA; a,

CRANK-CASE el man.

Application filed Gctober 3, 1927.- Serial No 223,702.

The present invention is directed to improvements in automobile crank case drainers.

The primary object of the invention is to provide a device of this character-seconstructed that it can be conveniently placed under or along the sideslof an automobile crank ease andoperated to remove the drain opening plug, whether the same is carried in the side or bottom of the crank case.

The invention is an improvement of our copending application filed December 23, 1926, Serial. No. 156,672.

In the accompanying drawings:

Figure 1 is a side elevation, partly in section, showing the device in its operative position.

Figure 2 is a similar view showing the device after the plug has been removed.

Figure 3 is a top plan view.

Figure 4C is a detail view of the handle mounting.

Figure 5 is a sectional view on line 55 of Figure 1.

Referring to the drawings, 1 designates a pan, preferably oval in shape and having mounted therein an interiorly threaded post 2 rising from the bottom thereof, the upper end of which is provided with spaced cars which support the bolt 4, the purpose of which will be later explained. a

A tubular handle 5 is provided and is r0- tatably engaged adjacent its lower end in a,

collar 6 in which is formeda plurality of recesses 7, said collar having fixed thereto a. transverse sleeve 8 for pivotally engaging he bolt 4.

A pair of brackets 9 are carried by the handle and slidable therein is a spring actuated latch rod 10 which is adapted to have its lower end selectively engage the perfora head 16. A beveled gear 17'is journaled on the bolt 18 carried by the housing and is adapted to mesh with the gear-14, said gear havinga squared'head 19 carried-thereby for detachably engaging the socket member 20.

A driving shaft 21 is mounted in the handle 5 and has fixedupon its lower enda beveled gear 22 which meshes with the gear in order that when the driving shaft is rotated by the handle 23 carried bythe upper end thereof, rotary movement will be transmitted to the driven shaft 13 to simultaneously rotate the socket memberand the socket member 24 engaged with the head 15. twill be ofcoursennderstood that these socket members are removable and,

vary in size to fit plugs 24" of various sizes which are employed for closingthe drain. openingsof the crank case 25.

In order that the pan 1 can be elevated when necessary a post 26 is threaded in the bolt '2 and is provided with a base 27 for enga ement with the floor.

Briefly, the operation is as follows:

The pan'l is placed under the crank case should the plug be in the bottom thereof, and the handle is rocked downwardly so that thesocket member 24 will engage the plug 24: and upon rotating the shaft 21 and the shaft, 13 the plug will be unscrewed and retained in the socket member, and is then swung upwardly to move the plug from under the drain opening to permit the oil to flow into the pan 1; After the crank case has been drained the handle is swung downwardly to place the plug in a position to be screwed in the drain opening, this being accomplished upon reversing the rotation of the respective shafts.

Owing to the presence of latch rod 10 and the pivotally mounted collar 6 the housing be swung backwardly and forwardly and laterally in order that the housing 12 may be easily and moving the plug;

In Figuresv 1 and 2 ofthe drawings, the

device is shown used in connection with? plugs in the .bottom'of a crank case, but in quickly positioned for re instances where the "plug is located in the I side of the crank case the socket member 20 is used. 1

Having thus described the invention, we claim:

loo

1. A' device for removing and replaeing the handle, and means for operating the driving shaft and thus the driven shaft.

2. The combination of a device for removing and replacing drain plugs of crank cases, of a pan, a post carried by the pan, a collar pivotally engaged with the post, a handle rotatable in the collar, means carried by the handle for normally engaging the collar to hold the handle against rotation, a driving shaft associated with the handle, and a driven shaft actuated by the driving shaft.

3. A device for removing and replacing drain plugs of crank cases, the combination with a pan, of, a 0st rising from the pan, a collar pivotally connected with the post, a tubular handle rotatable in the collar, a latch rod carried by the handle for interlocking engagement with the collar, a driving shaft rotatable 1n the handle, a housing supported by the handle, a driven shaft in the housing, and driven by the driving shaft, and means carried by the driven shaft for engaging a plug. I

4:. A device for removing and replacing drain plugs of crank cases, the combination with a pan, a post carried by the pan, a driven shaft, a driving shaft connected with the driven shaft, said driving shaft being pivotally connected with the post, and a second post threaded in the first named post, as and for the purpose set forth.

In testimony whereof We affix our signatures.
